comprisesa weighing tank which rests on the platform of the weighing scale, and a receiving tank into which the milk from the weighing tank is discharged, the receiving tank being of somewhat greater capacity "than the weighinggtank'so that all of the weighed milk in said weighing tank maybe discharged at one timeinto the receiving tank. This apparatus, with such a lar'e receiving tank, necessitates locating t e weighin tank at such a height that the milk cans to be emptied into said weighing tank have to be lifted to an inconvenient height.

This invention has for its object to provide a milk weighing apparatus which is compact, so that it is-convenient in use, and

inthe operation of which it will not be necessary to lift the milk cans to any-inconvenient height. To this end the weighing tank is provided with an outlet having a manually controlled valve which may be opened when milk is to be dischargedtherefrom into the receiving tank placed below it.

The outlet, in the present case, is in the form of-a discharge tube, and the receiving tank contains a float the top of which is provided with a valve which will be lifted with said float so as to fit against a Valve seat at the lower end of the discharge tube which is mounted on the weighing tank. \Vhen the amount of liquid accumulating in the receiving tank rises to a certain height, the float is lifted so as to close the discharge tube or outlet from the weighing tank, thuspreventing overflow of the relatively small receiving tank.

is a side view,partly brokenaway, of the improved apparatus.

Referring to the drawings, 12 denotes a framework comprising standards and-connecting bars all of which may be oftubularv construction. A platform scale is located within this framework and may be mounted on bars at the base thereof so as to be supported thereby. As shown in Fig. 1, 13 de- 1 notes a part of the platform of the scale,14; the standard thereof and 15 the scale beams. The weighing tank 16 is provided with U- shaped bars 17 the bottoms of which rest on the platform of the scale.

The weighing tank 16 is provided with an outlet or discharge tube 18 having valve seats 23 and 23 at its top and bottom, re-

with the lower end of a hand lever 26 which p Y may be operated to raise and lower the valve 22. 1 5

Located below the weighing tank 16is a receiving tank 27 which contains a float 28 the top of which is providedwith a valve 29 adapted,- when'the said float is lifted, to

fit against the 'lower valve seat 23 of the discharge tube 18. g Connected with the receiving tank 27, by pipes 28 and 29, is a pump 3O which-may be 9 driven by anelectric motor 31. A pipe-33 may be connected with thedischarge outlet 32 of the pump 30 and through which pipe the milkwill'be forced to any suitable' 'reservoiror receiving vat. I

In the operation of this milk weighing apparatus the milk to be weighed will be poured from the cans into the weighing tank 16, and-after the weighing of the milk has been registered the valve 22 willbeilifted manually so as to enable the milk in said tank i to be discharged into the receiving tank 27. The pump being now in operation the milk will be drawn from the'said receiving'tank, but should the liquid in'the tank rise to a height which would'endanger an overflow theiloat 28Lwillbeilifted causv ing the valvezi29 atathe top of said floatzto close the lower end of the discharge or outlet tube 18. When, due to the operation of the pump, the liquid in the receiving itank falls low enough to lower the float 28, the

lower end of the discharge tube =;will be opened and the discharge of the liquid from the weighing tank to the receivingtank will ithell be :resumed. V
